### Abstract

We present a framework for the automatic determination of synchronization and aliasing properties of a functional language extended with concurrency constructs (a subset of Concurrent ML). Synchronization properties state which processes, and at what process histories, may be simultaneously active during evaluation. Aliasing properties state which data, on what processes and at what process histories, may be shared. First, we develop a semantics in which the usual arbitrary set of channel identifiers is rendered unnecessary by a semantic notion of aliasing, and in which the usual arbitrary set of process identifiers is rendered unnecessary by a semantic notion of process history as control path. The result is a semantics in which synchronization properties and aliasing properties are mutually dependent, and this provides a rich framework for reasoning about t...
